ADVERTISING ATTACHMENT FOR MUSIC-BOXES.

SPECIFICATION forming part of Letters Patent No. 624,397, dated. May 2, 1899.

Application filed June 27,1898. Serial No. 684,606. (No model.)

To all whom, it may concern:

Be it known that I, ROBERT L. STANTON, a citizen of the United States, residing at Providence,in the county of Providence and State of Rhode Island, have invented certain new and useful Improvementsin Advertising Attachments for Music-Boxes, of which the following isa specification, reference being had therein to the accompanying drawings.

Like numerals indicate like parts.

box' provided With my improved advertising apparatus when all the parts are in operative position. Fig. 2 is a perspective view of the same when the advertising device is not in operative position, but is elevated out of connection with the tune-sheet of the music-box. Fig. 3 is aview in side elevation of the tunesheet and means for rotating the same, together with the ad vertising-disk, the frictionroller, and tension-roller of my device, all as seen on line y y of Fig. 5 in the direction of the arrows there. Fig. 4 is a top plan of the arm and its hingedsupport and the guiderollers, together with the friction-roller and tension-roller of my device. Fig. 5 is a top plan of my improved advertising apparatus mounted in operative position within the case of a m usic box above and parallel to the tunesheet, the circumferential edge of which is also shown in said figure. Fig. 6 is a top plan of the advertising-disk with one of the detachable sections thereof removed. Fig. 7 is a perspective view of such removed section. Fig. 8 is a view of portions of said advertis: ing-disk and tune-sheet, together with a portion of the arm for said sheet, and illustrates how said advertising-disk and tune-sheet are mounted, the view being that on line at a; of Fig. 6.

My invention is a device for displaying advertisements, and is adapted to be used in connection with a music-box and to derive from the mechanism thereof a rotary movement, by which said advertisements are consecutively brought into position to be read.

In the drawings my invention is shown in the form best suited for use with that kind of a music-box in which a rotating tune-sheet which produce the musical tones.

- upon the stud 4.

With this in View my invention consists of a music-box having a revolving member, which is adapted to vibrate the soundingtongues, in combination with a disk or frame provided with means for holding advertising 1 sheets or plates in position thereon and 1'0- 1 tatable upona fixed pivot and means to communicate motion from said revolving member to said disk or frame to rotate the latter,

as hereinafter particularly described.

The box or case of the music-box is shown The tune-sheet 3 is a metallic disk centrally mounted rotatably It is circular in form and has near its edge, all around, the holes 5,which are engaged by the spurs of the sprocket-wheel 6. The revolution of this sprocket-wheel 6,

caused, as usual, by the spring within the box, results, by reason of the said engagement with the holes 5 of the tune-sheet 3, in the rotation of said sheet or disk, and such rotation causes the sheet or disk, which is made with radial slots or projections, to operate the sounding-tongues in the well-known manner.

A plate 7, having a diametrically-slotted post 8, is fastened by screws 9 to the platform 10 of the music-box 1. An arm 11, having one end thinned and adapted to enter the slot of the post 8, is there pivotally mounted by the pin 12 and is movable in a vertical plane from'the horizontal position shown in Figs.

3, 4, and 8 to the elevated position illustrated in Fig. 2. Said arm 11 is provided with friction-rollers 13, and at its inner end it has a centrally-recessed head 14:,w'hich receives and rests upon the stud 4, as seen in Fig. 8. Said arm is secured in place upon the stud 4 by means of a catch, (shown in Fig. 8,) which is movable through the head 14 into a slot in the stud 1.

Guide-rollers 15 15 are mounted rotatably upon the stud-pins 16 16 of spring-pressed levers 17 17, which extend from the arm 11.

These rollers 15 serve to press the sheet or disk 3 downward toward .and upon the sprocket-wheel 6, as shown in Fig. 3, so as to enable the proper engagement of the sprockets with the holes 5 of said disk or sheet.

All the parts thus far described are in the well-known form and are placed as usual in music-boxes of this class.

. Myinventionis an attachment for such U111 sic-boxes and is described as follows: 7 An advertising-disk.('which I designate comprehensively as 18) is composed of two parts arranged one upon the other, the lower part consisting of a circular ring 19 and two diametrical cross bars or ribs 20, placed at right angles with each other, as seen in Figs. 5 and 6. The upper portion consists of two crossbars 2O at right angles with each other, as shown in Figs. 5, (3, and 7. At the meeting place, at the middle of these cross-bars, are central apertures through which a pivot 21 passes, having a knurled head and a cylindrical shank and a screw-threaded end of less diameter than said shank, the screw-threaded end engaging in a screw-threaded hole tapped in the head 14 of the arm 11., all as plainly illustrated in Fig. 8. The advertising-disk is thus rotatable upon the cylindrical shank of the pivot 21. The cross-bars 20 are somewhat cut away on their inner 0r contiguous surfaces, as seen in Fig. 8, to allow the insertion there of advertising sheets or sections 22, and said arms are secured together by the screws .23. These screws also serve to hold the advertising sheets or sections -firmly by compression between said crossarms. Each advertising sheet or section 22 is in the form .ofa quarter-circle, (see Fig. 7,) except that, preferably, the inner edge is concave or cut concentric or parallel with the outer edge. The two straight edges thereof are received between and held by the upper and lower cross-bars, respectively, as shown. On each advertising piece or section 22 is displayed an advertisement 24. These adver tising-sheets are preferably of pasteboard or other suitable opaque material, but may be of glass, if desired, as indicated in Fig. 2, in which case their transparencyallows a view of the tune-disk, which is movingbeneath them/ A slotted bar 25 is mounted on a post 26 of the arm 11 and held adjustably thereon by a screw 27. Said bar 25 is twisted a quarterturn and at its outer end has a stud 28, on which is mounted a feed-roller 29.

A tension-roller 30 is mounted on a screwpivot 31 upon a post 32 of a base or plate 33 upon the platform 10 of the music-box 1. Said base-plate 33 is secured in position by a screw 34.

The post 32 is slotted, as indicated at 35 in Fig. 3, so that the tension-roller 30 may be adjusted in height by means of the screwpivot 31.

The advertising-disk is caused to rotate in a horizontalplane in a direction opposite to that of the rotation of the tune sheet or disk 3 by means of the friction-roller 29, Fig. 3. When the tune sheet or disk 3 is rotated by the sprocket-wheel 6 in the usual manner, such rotation revolves the friction-roller 29, which rests upon the tune sheet or disk 3. The ring portion 19 of the advertising-disk rests upon the top of said friction-roller '29 and the revolution ofthe latter, caused, as aforesaid, by the rotation of the tune-sheet 3,

turns the advertisingsdisk in a direction opposite to that of the movement of the tunesheet 3. This rotary movement of the advertising-disk brings consecutively to the front and into reading position the several advertisements 2 L thereon.

As the tune-sheets 3 when made, as usual, of sheet metal are not perfectly flat, but are liable robe sprung or bent somewhat out of true plane, it is desirable to provide a tension-roller, as 30, which, being properly adjusted in height, presses up the disk or sheet 3 and insures'a firmer frictional hold thereon by the roller 29 and a more uniform move- I ment of the advertising-disk in relation to that of the music-disk 3.

This advertising device is most useful when used in connection with a coin -controlled music-box. The person who has deposited the coin in the m usic-box to operate thesame gives attention not only to the tune which is played, but. also to the advertisements, which are movingat the same time, and the novelty of the device and the opposite'direction of travel of the two disks, as well as his curiosity to ascertain the cause of such diverse movements, serve to attract his attention to the advertisements themselves, and thus the device is a "aluable means of advertising to hilfi and the bystanders, who generally gather about to listen to the music, the various kinds of business or merchandise which may be set forth on the advertising-sections.

In case it is desired to have the advertisingdisk rotate in a vertical plane the mechantally-revolving tune-sheet by any of the methods well known to mechanics; but such modification would be within the scope of my invention and the mechanical principle thereof.

I claim as a novel and useful invention and desire to secureby Letters Pate-nt- 1.
